I first heard this song in one of the episodes of Crossing Lines (on Netflix), and thought this was a cool song. The Youtuber sharing this MV noted this song was written and produced by Susie Suh and Robot Koch, but not yet released.
I'm not familiar with either Susie Suh or Robot Koch. According to Wikipedia, Susie Suh is a Korean-American adult alternative/folk-rock singer-songwriter, while Robot Koch is a music producer based in Berlin, Germany. This MV is also on http://www.susiesuh.com/, so it looks like it is still not released yet.
Anyway, have a listen here and let us know what you think.
